BACKGROUND OF THE INVENTION

A. Field of the Invention

The present invention relates generally to topical skin compositionsthat can be used to reduce the appearance of shiny or oily skin or thatcan be used to increase the wearability of cosmetic compositions.

B. Description of Related Art

Human skin naturally manufactures and secrets an oily substance calledsebum from sebaceous glands located near the skin surface. Sebumlubricates and protects skin against moisture loss by forming a filmover the surface of the skin. A build-up of sebum on the surface of skincan cause the skin to appear shiny or oily. Besides the visuallyunappealing appearance of shiny or oily skin, sebum build-up can alsohighlight skin imperfections, promote skin acne development, and reducethe wearability of cosmetic compositions such as foundations.

Current methods that are used to reduce the amount of sebum on thesurface of skin include increasing the consumption of water, applyingmoisturizers to skin, and using compositions that attempt to absorbsebum from skin. Problems associated with current sebum absorptioncompositions is that the absorbing ingredient(s) tends to coalescetogether which causes the composition to cake or streak on the skinsurface.

SUMMARY OF THE INVENTION

One aspect of the present invention concerns a composition that canprovide sebum absorption from the skin while avoiding the unsightlycaking or streaking that has been seen in previous sebum absorptioncompositions. One of the aspects of the composition is that thecomposition can include only two ingredients (although several otherscan be added as explained throughout the specification). In particularembodiments, the concentration ranges of the ingredients can play a rolein preparing a sebum absorption composition that is tailored toparticular skin types (e.g., oily skin, normal skin, normal to oilyskin, normal to dry skin, dry skin, etc.).

In one embodiment of the present invention, there is disclosed a sebumabsorption composition that includes 1% to 20% by weight of thecomposition of a sebum absorption ingredient; and 20% to 99% by weightof the composition of a volatile solvent.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

In today's image conscious society, people are continually looking for aproduct that can improve the visual appearance of their skin. Oftentimes, skin overproduces sebum which can cause skin to appear oily orshiny and have a slippery feel. The build-up of sebum can also resultfrom normally functioning sebaceous glands in instances where the skinhas not been washed for an extended period of time. Besides the visuallyunappealing appearance of shiny or oily skin, sebum build-up can alsohighlight skin imperfections, promote skin acne development, and reducethe wearability of cosmetic compositions such as foundations.

Disclosed is a sebum absorption composition that can absorb or removesebum from the surface of the skin. As explained in non-limiting aspectsin the following sections, the composition can comprise, consistessentially of, or consist of a sebum absorption ingredient and avolatile solvent. The concentration ranges of these ingredients can bevaried to particular skin types (e.g., oil skin, dry skin, normal skin,etc.). In this regard, the compositions can be made to a particular skintype. In certain non-limiting embodiments, the composition can includeonly two ingredients (e.g., sebum absorption ingredient and a volatilesolvent) and still be effective in removing or absorbing sebum from thesurface of the skin, while also maintaining pharmaceutically and/orcosmetically elegant properties. This has the particular advantage ofreducing the costs associated with obtaining the ingredients andpreparing such a composition (i.e., only two ingredients can be used toachieve a desired result).

Example 4 Shine Control Data

Overview of Study: A study was conducted to determine the efficacy ofthe Composition in Table 3 to control the appearance of shiny skin overa six (6) our period.

Study Protocol: Nineteen (19) adults were enrolled and completed thestudy. Panelists were asked to not apply any product, other than thetest formulation illustrated in Table 3, to the forehead for theduration of the study. Panelists washed their face with the providedcleanser prior to having any measurements taken. A baseline shinereading of the forehead was taken at the initial visit. Panelists thenapplied the test product to the entire face. A second shine reading wastaken immediately after product application. A final shine reading wastaken 6 hours after product application. Each panelist was also given aquestionnaire regarding their perception of shine at the baseline and 6hour evaluations. The baseline, immediate, and 6 hour measurements weretaken using the Konica Minolta Glossmeter (per Biophysical SOP 005).

Results: The mean % reduction in skin surface shine from the baselinemeasurement was 41% after immediate application and 17% after six (6)hours from application of the test formulation illustrated in Table 3(note: statistically significant at ≧95% confidence level. The Resultsare also illustrated in FIG. 2 (note: D930-04 is the Table 3formulation). These data illustrate that the Table 3 formulationsignificantly reduced shine on the skin at the immediate and six (6)hour readings.
